[Decompilation] [th01] HUD: Inter-page row-sized rectangle blitting
Both inlined and non-inlined page switching within the same function, together with an approach that doesn't correspond to our other planar access macros? That code must have been written during a very experimental phase very early in the development of this game. Part of P0104, funded by Ember2528.
